Copying a jagged array

[Dr1ZZ]

I've made this short test code, to illustrate my problem:

int[][] j = new int[2][];
j[0] = new int[] { 0 };
 
int[][] k = (int[][])j.Clone();
 
k[0][0] = 1;
 
Console.WriteLine("j: "+j[0][0].ToString());
Console.WriteLine("k: " + k[0][0].ToString());
 

The program writes out both j and k as 1, where it should write j as 0.

I've tried with both Clone, CopyTo and Array.Copy, all with the same result.

Anyone who can tell me what im doing wrong?

            int[][] j = new int[2][];
            j[0] = new int[] { 0 };
 
            int[,] k = new int[1,1]; // = (int[][])j.Clone();
 
            k[0,0] = 1;
 
            Console.WriteLine("j: " + j[0][0].ToString());
            Console.WriteLine("k: " + k[0,0].ToString());

Try this.

You're creating an entirely new array (multidimensional instead of jagged), why?

I'm sorry I didnt explain it in my post, but i thought the code illustrated it well enough.
What I want is a copy of my original jagged array, but instead it references to the original, even when I'm using Clone/CopyTo/Array.Copy

Ehm ok, why if I may ask? :/

Sorry I said the thread which I post.
